    摘要: PURPOSE:To sensitize the titled material by adding a specified macrocyclic amine compound to the silver halide emulsion layer. CONSTITUTION:To a silver halide emulsion layer is added a compound represented by general formulaI(where each of R1, R2, R3 and R4 is H or 1-3C lower alkyl, they may be identical with or different from each other, yet all of them are not H simultaneously, and each of X1, X2, X3 and X4 is a carbon chain consisting of at least 2C atoms). The preferred amount of the added compound is about 0.01mg-40g per 1mol silver halide. The increased amount of the added compound causes no increase in fog, and even in the emulsion layer is allowed to stand under severe conditions after coating, the fog is not increased and the sensitivity is not reduced.

    摘要: PROBLEM TO BE SOLVED: To obtain a new compound suitable as a chitinase inhibitor usable for an antimicrobial agent, an inspecticide, an agrochemical, an agent for animal, a ship bottom coating material, etc. SOLUTION: This compound is shown by the formula. The compound of the formula is obtained, for example, by subjecting a sponge to an extraction treatment with acetone, methanol, water, water-containing methanol, water- containing ethanol, etc., and by using column chromatography, high-performance liquid chromatography, etc., with an ion exchange resin, activated carbon, a gel filtration medium, silica gel, chemical bond type silica gel, etc.
